Abstract

Introduction: Hypertension is a chronic disease with 31% worldwide prevalence in adults. It has been associated with non-adherence to therapeutic regime with a negative impact on the prognosis of the disease and healthcare-associated costs. So, it is necessary to identify effective interventions to improve adherence among the afflicted population. The objective of this protocol is to describe the methods for a systematic review that will evaluate the effect of individual interventions so as to improve adherence to the prescribed pharmacological treatment, as well as to prescribed diet and physical activity in adults with primary hypertension.

Methods and analysis: A systematic search of studies will be conducted in PubMed/MEDLINE, BVS, CINAHL, Embase, Cochrane and Scopus databases. Randomised and non-randomised clinical studies conducted in human beings, published from 1 January 2009 to 13 December 2019, are to be included, in any language. Adherence to pharmacological treatment, diet and physical activity, measured by direct and indirect methods, will be the primary outcome. Two independent reviewers will select relevant studies and will extract the data following the Cochrane's Handbook for Systematic Reviews of Approach and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols. Methodological quality will be evaluated using the risk-of-bias (RoB) 2 and Risk of Bias in Non-randomised Studies - of Interventions (ROBINS-I) tools. Risk of bias will also be evaluated, and if the criteria are met, a meta-analysis will be finally performed.

Ethics and dissemination: Information to be analysed is of a grouped nature, and given that its sources are published studies, no ethics committee approval is required. Results will be published in scientific journals, and in conferences, seminars and symposiums. Copyrights will be addressed by giving due credit through bibliographic references.
